Set up a VPN for remote access to workplace applications

Some companies require employees to use virtual private networks (VPNs) to access applications while out of the office. Even if not a technical requirement, though, it’s a good idea to use a VPN so that you avoid risks such as data interception from man-in-the-middle attacks, as well as ISP surveillance. VPNs are available as both paid subscriptions from dedicated providers and as utilities built into some web browsers, like Opera.
